The traditional role of a bishop is to act as head of a diocese or eparchy. Dioceses vary considerably in geographical size and population. A wide variety of dioceses around the
Mediterranean Sea which received the Christian faith early are rather compact in size, while those in areas more recently evangelized, as in some parts of
Sub-Saharan Africa,
South America and the
Far East, tend to be much larger and more populous. Within his own diocese a Latin Church bishop may use pontifical vestments and regalia, but may not do so in another diocese without, at least, the presumed consent of the appropriate ordinary.
Appointment Resignation at 75 Since the
Second Vatican Council of 1965 diocesan bishops and their equals "who have become less capable of fulfilling their duties properly because of the increasing burden of age or some other serious reason, are earnestly requested to offer their resignation from office either at their own initiative or upon the invitation of the competent authority." The age of 75 was suggested, and
John Paul II had these provisions incorporated in the
Latin Church's new
1983 Code of Canon Law. Article 401.1 of the 1983 Code of Canon Law states that "A diocesan Bishop who has completed his seventy-fifth year of age is requested to offer his resignation from office to the
Supreme Pontiff, who, taking all the circumstances into account, will make provision accordingly". On 15 February 2018, Pope Francis established the same rule for non-cardinal bishops serving in the
Roman Curia, who had previously lost their positions automatically at 75.
Roles A "diocesan bishop" is entrusted with the care of a
local Church (
diocese). He is responsible for teaching, governing, and
sanctifying the faithful of his diocese, sharing these duties with the priests and deacons who serve under him. The Second Vatican Council's
Constitution on the Sacred Liturgy described the diocesan bishop as "the high priest of his flock". To "teach, sanctify and govern" means that he must (1) oversee preaching of the Gospel and Catholic education in all its forms; (2) oversee and provide for the administration of the sacraments; and (3) legislate, administer and act as judge for
canon-law matters within his diocese. He serves as the "chief
shepherd" (spiritual leader) of the diocese and has responsibility for the pastoral care of all Catholics living within his ecclesiastical and
ritual jurisdiction. He is obliged to celebrate
Mass every Sunday and
Holy Day of Obligation with the intention of praying for those in his care, assign clergy to their posts in various institutions and oversee finances. A bishop is to have a special concern for priests, listening to them, using them as counsellors, ensuring that they are adequately provided for in every way, and defending their rights set forth in the
Code of Canon Law. Latin Catholic bishops also must make regular
ad limina visits to the Holy See every five years. Because of their function as teachers of the faith, it is customary in some English-speaking countries to add to the names of bishops the postnominal title of "D.D." (
Doctor of Divinity) and to refer to and address them as "Doctor". Only a bishop has authority to confer the
sacrament of holy orders. In the Latin Church the
minor orders were abolished after the Second Vatican Council. In Eastern Catholic Churches, a monastic
archimandrite may
tonsure and institute his subjects to minor orders; however, the tonsure and minor orders are not considered to be part of the sacrament of holy orders. The sacrament of
Confirmation is normally administered by a bishop in the Latin Church, but a bishop may delegate the administration to a priest. In the case of receiving an adult into full communion with the Catholic Church, the presiding priest will administer Confirmation. In the Eastern Catholic Churches, Confirmation (called
Chrismation) is normally administered by priests as it is given at the same time as
baptism. It is only within the power of the diocesan or eparchial bishop to bless
churches and
altars, although he may delegate another bishop, or even a priest, to perform the ceremony. On
Holy Thursday, Latin Catholic bishops preside over the
Mass of the Chrism. In some cases this celebration takes place on the preceding
Wednesday. Although Oil of the Sick for the sacrament of
Anointing of the Sick is blessed at this Mass, it may also be blessed by any priest in case of necessity. Only a bishop may consecrate Chrism. In the Eastern Catholic Churches chrism is consecrated solely by heads of churches
sui juris (patriarchs and metropolitans) and diocesan bishops may not do so. Only a bishop or other ordinary may grant
nihil obstats for theological books, certifying that they are free from doctrinal or moral error; this is an expression of the teaching authority and educational responsibility of the bishop. Prior to the
Second Vatican Council, it was also the prerogative of the bishop to consecrate the
paten and
chalice that would be used during the Mass. One of the changes implemented since the council, is that a simple blessing is now said, and it may be given by any priest.
Canonical authority In both Western and Eastern Catholic churches, any priest can celebrate the
Mass or
Divine Liturgy. In order to offer Mass or Divine Liturgy publicly, however, a priest is required to have permission from the local Ordinary—authority for this permission may be given to pastors of parishes for a limited period, but for long-term permission recourse to the diocesan bishop is usually required. A
celebret may be issued to travelling priests so that they can demonstrate to pastors and bishops outside of their own diocese that they are in good standing. However, even if a priest does not possess such a document, he may celebrate the sacraments if the local bishop or pastor judges that the visiting priest is a person of good character. In the East an
antimension signed by the bishop is kept on the altar partly as a reminder of whose altar it is and under whose
omophorion the priest at a local parish is serving. In the Western Catholic church's view of bishops' powers, the "power which they exercise personally in the name of Christ, is proper, ordinary, and immediate, although its exercise is ultimately controlled by the supreme authority of the Church," as per
Lumen Gentium 27. however, when the penitent is in danger of death, a priest has both the right and obligation to hear the confession no matter where he may be. To preside at matrimony ceremonies, Latin Church priests and deacons must have appropriate jurisdiction or delegation from a competent authority. In the Latin branch of the Catholic Church, the teaching is that it is the couple themselves who administer the graces of the sacrament; thus, although it is normally an ordained person who officiates at a marriage ceremony, a bishop may delegate a lay person to be present for the exchange of vows; this would be done only in extreme cases such as in mission territories. In the Eastern tradition, the clergy not only witness the exchange of vows but must impart a blessing for a valid marriage to have taken place. Unless a particular bishop has forbidden it, any bishop may preach throughout the Catholic Church and any priest or deacon may also preach anywhere (presuming the permission of local pastor) unless his faculty to preach has been restricted or removed. The
cathedral of a diocese contains a special chair, called a
cathedra, sometimes referred to as a
throne, set aside in the sanctuary for the exclusive use of its Ordinary; it symbolizes his spiritual and ecclesiastical authority. == Additional titles, status and roles ==
